Credit for Taxes Paid to Another State
Live in one state, work in another. This estimates what each state takes, how much of the double tax the resident credit actually relieves, and whether a reciprocity agreement means you never had to file at all.
How much credit do I get for taxes paid to another state?
You would owe about $6,181 to New York as a nonresident and $5,454 to New Jersey as a resident, less a credit of $5,454 — a combined $6,181. About $727 of the New York tax exceeds what New Jersey would have charged and is not recoverable.
- The credit is the LESSER of tax paid to the work state or your home state's tax on the same income
- Reciprocity pairs skip the credit entirely — file an exemption certificate instead
- California pairs with AZ, OR and VA in reverse: the source state grants the credit
- A higher-tax work state leaves unrelieved tax the credit cannot reach
- Convenience-of-the-employer states can tax work-from-home days you never spent there

Where you live and work
Head of household isn't modelled separately. HOH filers get a larger standard deduction and, in states such as California and New York, wider brackets, so choosing Single may run high for you.

The lesser-of test
Tax paid to New York: $6,181 · New Jersey tax on the same income: $5,454. The credit takes the smaller figure.
$727 of New York tax exceeds the credit cap. Neither state refunds it — this is the real cost of working in a higher-tax state.
New York convenience rule. The strictest version, and the one that generates the most controversy. Days worked from a home office outside New York are New York days unless the home office meets the Department’s bona-fide-employer-office test (TSB-M-06(5)I).
What this means for your filing
- The credit is capped by what New Jersey would have charged on the same income. The extra New York tax above that cap is not refundable by either state — it is a permanent cost of working in the higher-tax state.
- You file two returns: a New York nonresident return reporting the New York-source wages, and a New Jersey resident return reporting all income and claiming the credit. File the nonresident return first — the residence state's credit schedule asks for the tax shown on it.
- Approximation: each state’s tax uses its own taxable-income base (standard deduction, personal exemptions and exemption credits for a filer with no dependents, the same base as our take-home and paycheck calculators) and a straight income-share apportionment. States differ on how the numerator and denominator are defined, whether itemized deductions and personal exemptions are apportioned, and whether local taxes count toward the credit. Use this as a planning estimate, not as a filed figure.
- New York applies a convenience-of-the-employer rule. If any of these wages are for days you worked from home outside New York, New York may still treat them as New York source income, and your residence state may not credit that portion.
Methodology & limits
The work-state figure uses the apportionment method most states apply to nonresidents: compute the tax as though all income were taxable there, then multiply by the share of income sourced to that state. The residence-state figure is the tax on all income, and the credit limb is that tax multiplied by the same share.
Where states diverge — the exact definition of the numerator, whether exemptions and itemized deductions are apportioned, per-state versus aggregate credit computation, and whether local taxes count — this tool applies the general rule and flags the result as an estimate. It does not model local income taxes such as New York City, Philadelphia, Ohio municipal tax or Indiana county tax, none of which are generally covered by a state-level credit or by reciprocity.
Two categories are refused rather than approximated: reciprocity pairs, where no credit exists, and reverse-credit pairs, where the credit direction flips. Both are cited to the relevant revenue department in the sources below.
Frequently asked questions
- How does the credit for taxes paid to another state work?
- Your residence state taxes all of your income wherever it was earned. The state where you worked taxes the portion earned inside its borders. Your residence state then gives you a credit, limited to the LESSER of the tax you actually paid to the work state or the tax your residence state itself charges on that same income. The credit relieves the double tax but never refunds more than your home state was going to collect.
- Do I have to file two state tax returns?
- Usually yes — a nonresident return in the state where you worked and a resident return at home. File the nonresident return first, because the resident return's credit schedule asks for the tax shown on it. The exception is a reciprocity state pair, where you file only the resident return once the exemption certificate is on file with your employer.
- What is a reciprocity agreement?
- An agreement between two states that wages earned by a resident of one while working in the other are taxable only by the residence state. Pennsylvania and New Jersey have one, as do Maryland with Virginia, DC and West Virginia, and Illinois with Iowa, Kentucky, Michigan and Wisconsin. You file an exemption certificate with your employer, the work state stops withholding, and no credit computation is needed at all.
- Can I be taxed twice on the same income?
- In the ordinary case, no — the credit prevents it. But two situations produce genuine unrelieved double tax. First, when the work state's rate exceeds your home state's, the credit is capped at your home state's tax and the excess is simply lost. Second, the convenience-of-the-employer rule in New York and a handful of other states can source your work-from-home days to the employer's state while your home state also taxes them.
- Why does California work backwards?
- California pairs with Arizona, Oregon and Virginia as reverse-credit states (Indiana was dropped for taxable years beginning on or after January 1, 2017 and now follows the ordinary rule). In those pairings the SOURCE state grants the credit rather than the residence state, so a California resident with Arizona income claims the credit on the Arizona return. Applying the ordinary rule to these pairs produces a materially wrong number, which is why this calculator refuses to estimate them and points you to the right form instead.
